Not necessarily true. It applies to a few, but most players didn't come for the money. They came because it was too good to pass a chance at playing for Inter. Plus their wives had a say since they wanted to live in Milano instead of Liverpool, Manchester, Valencia, La Coruña, Marseille, Lyon, Munich, Gelsenkirchen, Hamburg, Rome or Turin over the years.
Inter under Moratti was a top 5-6 destination for players. And it wasn't about the money. Others paid better. Moratti did pay well but he paid his stars well, everyone else weren't really higher earners than those at rival clubs.
Of course they wouldn't come on a discount, but they weren't asking Inter to match higher bids. They were usually happy with our terms.
